The compact keyboard combines 8,000 Hz communication with low-profile switches. October's review raises concerns beyond the wireless connection.

The connection stands out; the whole keyboard matters
The Cherry XTRFY K63W Pro Compact puts a technology rarely seen in keyboards at the center of the conversation: Ultra-Wideband, or UWB. The idea is to bring 8,000 Hz wireless communication to a small, low-profile board for a gaming desk. Choosing a keyboard also involves key feel, connection options and how easily it can be maintained.
The product had already officially launched on July 2. A review by Nikita Achanta, published on Tom's Guide on October 9, now puts those choices back under scrutiny. It is a fresh test of a model that was already on the market.
What UWB brings to the desk
According to Cherry's technical explanation, UWB sends data in short pulses spread across a broad frequency range. The manufacturer presents it as a way to reduce interference from other wireless devices. The keyboard uses its own receiver plugged into the computer.
The 8,000 Hz rate is available both wired and wirelessly. It describes how often the keyboard communicates with the PC, not a complete measurement of the delay between pressing a key and seeing the action onscreen. That figure alone cannot prove a noticeable advantage in every match or establish a latency result that has not been measured.
Small, with the function row intact
The Cherry XTRFY announcement describes a 70% layout that keeps the F-key row and trims the sides to leave more room for a mouse. The switches are Cherry MX Low Profile 2.0, and the gasket mounting uses elastic supports for the internal assembly.
Choices that matter after the match
There is no Bluetooth. Wireless use relies on the UWB receiver, a limitation worth considering if the keyboard needs to move between devices. The keycaps are ABS, and the switches are soldered. The official product page confirms that this model does not support hot-swapping.
Trying or replacing switches requires desoldering the original switches and soldering their replacements to the circuit board. They cannot simply be pulled from removable sockets.
Issues reported with the review sample
In the Tom's Guide review, Achanta praises the gaming experience but reports duplicate and missed inputs while typing. She questions whether her sample was faulty and says she contacted the company. In the version consulted, she was still awaiting a response.
That account deserves attention without becoming a diagnosis of every unit or of UWB itself. Prospective buyers should look for clarification about that sample and check the seller's return policy. The new connection is interesting; confidence in daily use still depends on each key doing what you expect it to.
